Unless the schematics of the chips went up in flames along with the cases, there would be some surviving evidence somewhere, but I'd imagine it's going to be quite rare.

One other option I've heard about is removing the surface a chip to take high resolution scans of the silicon itself, but I very much doubt that anyone at either of the two museums that have machines would allow anyone anywhere near theirs to do that, and I wouldn't blame them.

I do wonder how far through development of the Phoebe they were at the time of canning the product. How many actual machines had been built, how many boards, chips, components, etc. had been made, built, bought up, etc. ready for final fabrication.

It is such a shame that many of the details could be lost. If only someone could build a time machine and go back to 1998 and take backups of all the documentation, etc.

I used to wonder why nobody else has ever decided to build a replica of the machine. I reckon most people who've heard of Phoebe would be interested in owning one, even if it's newly built, purely to see what could have been.
